Value Collection -33619-1 Hex Socket Cap Screw 5/16-18 Unc

Product Description

The VALUE COLLECTION -33619-1 is a fully threaded hex socket cap screw designed for secure fastening in mechanical, industrial, and trade assembly applications. It features a 5/16-18 UNC thread size and a 1 inch length under head, making it well suited for moderate-load bolted connections. The screw is machined from alloy steel and finished with a black oxide coating that provides mild corrosion resistance and reduces light reflection. Drive engagement is via a 1/4 inch hex socket, compatible with standard Allen keys and hex bit drivers. Licensed tradespeople and maintenance technicians will find this fastener appropriate for equipment assembly, fixture mounting, and machine maintenance tasks.

This cap screw is used across a wide range of trade and industrial settings including HVAC equipment assembly, electrical panel fabrication, plumbing fixture mounting, and general mechanical maintenance. It is sold individually with a minimum order quantity of 50 pieces, making it practical for stocking in service vans, shop bins, or job-site fastener inventories where UNC-threaded alloy steel screws are frequently consumed.
